Can ETC Still Be Used After Being Removed and Reattached?

1 Answers

No, it cannot be used. The ETC device will become invalid once it is removed by the user because it is equipped with an anti-tamper feature. There is a small switch at the back of the ETC electronic tag, which automatically turns off once the device is peeled off the windshield. Therefore, you must take the vehicle's registration certificate to the ETC service provider for reactivation. ETC Billing Principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to settle transactions with the bank, achieving the purpose of paying tolls without stopping at the bridge or toll station. All of this operates on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions since vehicles do not need to stop at toll stations; Reduces wear and tear: Saves costs by minimizing frequent starts and stops, thereby reducing vehicle wear and fuel consumption; Improves efficiency: Theoretically, ETC lanes can process vehicles 2-3 times faster, making traditional ETC more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will also be made to promote ETC usage for trucks and explore deeper integration of the ETC system with smart transportation developments such as vehicle-to-vehicle communication and vehicle-to-infrastructure coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage. Precautions for Installing ETC: Do not obstruct the driver's view; it is best to install it behind the rearview mirror: Many car models have windshields with a steep incline, which can reduce the driver's field of vision. If ETC installation does not account for this, it may increase blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag requires power but generally does not need charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper rod connected to a switch. Once the electronic tag is installed on the windshield, the anti-tamper rod is pressed in. If removed arbitrarily, the rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This feature is designed to prevent multiple vehicles from sharing one device. ETC Usage Tips: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its faulty ETC device, maintain a distance of at least 10 meters. The ETC lane recognition speed is 20 km/h; driving too fast may result in failed deductions due to unreadable device information. If using a debit card linked to ETC, insufficient balance may also cause deduction failures.

Does a Car Key Need to Be Charged?

Car keys do not need to be charged. They use small batteries inside, which generally cannot be recharged. You can simply replace the battery, either at a 4S shop or by doing it yourself. If the key uses a coin cell battery, the owner can replace it directly at an after-sales service point or purchase a battery with the same specifications online and follow the key's instruction manual to replace the coin cell battery. Method for replacing the car key battery yourself: Purchase the original battery for the car key, ensuring the voltage and model match. Remove the mechanical key—usually by pressing a small button to pull it out. Use a small flat-head screwdriver to pry open the car key. There is usually a small gap in the middle of the key, and a gentle twist will open it. Remove the old battery and install the new one. Once done, reassemble the car key. Precautions for using car keys: Release the key immediately after starting the car. Holding it in the start position for too long can damage the engine belt. Avoid hanging the key with accessories, as collisions with them can gradually widen the keyhole gap. Do not expose the key to high temperatures or liquids.

What Causes Steering Wheel Vibration at Speeds Above 130km/h?

Tire dynamic imbalance, significant differences in tire pressure among the four tires, and poor four-wheel alignment can cause steering wheel vibration at speeds above 130km/h. Tire Dynamic Imbalance: If a tire experiences a strong impact in a localized area during driving, it can cause the balance weights to fall off or become damaged, thereby affecting the tire's dynamic balance. Significant Differences in Tire Pressure Among the Four Tires: When there is a large difference in tire pressure among the four tires, especially between the left and right wheels, the car will experience noticeable body jolts and steering wheel vibration during high-speed driving. Poor Four-Wheel Alignment: When the four-wheel alignment has significant deviation angles, the car may exhibit body drift and vibration during high-speed driving. This can also lead to uneven tire wear, accelerating tire wear and shortening the tire's lifespan. Solutions for Steering Wheel Vibration at Speeds Above 130km/h: When steering wheel vibration occurs at high speeds, the first step is to check and adjust the tire pressure. Next, perform a dynamic balance check on all four wheels, and finally, conduct a four-wheel alignment.

Should the Air Conditioning Be Set to Internal or External Circulation During Long-Term Parking?

Keeping the air conditioning on internal circulation during long-term parking will gradually lead to polluted air inside the vehicle, increasing harmful gases and posing risks to human health. It is advisable to periodically switch to external circulation or leave a small gap in the window to allow fresh air in. Continuous use of internal circulation can result in carbon dioxide poisoning. The choice between internal and external circulation should be adjusted based on actual conditions. Use external circulation on highways: First, due to wind resistance and high speeds, opening windows is not advisable on highways. Prolonged use of internal circulation can cause brain hypoxia, impairing reaction time and judgment, which is highly dangerous. Second, the air quality on highways is generally good, with low concentrations of exhaust fumes, making external circulation a suitable choice. In urban areas, during congested traffic or peak commuting hours when vehicle exhaust concentrations are high, it is best to switch to internal circulation. New cars typically contain high concentrations of toxic gases like formaldehyde. For the first three to six months after purchasing a new car, it is recommended to use external circulation along with opening windows to enhance air circulation and dilute the concentration of toxic gases inside the vehicle.

Do Cars Need Car Covers?

Car covers are necessary as they primarily serve to protect the car's paint and windows from direct sunlight exposure. They also provide protection against rain, snow, and falling leaves, while helping to keep the car clean. Precautions for Using Car Covers: It is best to use a car cover when the vehicle is stationary and the temperature has cooled down after washing. The cover should be of the right size to fit the car perfectly to ensure it functions as intended. Be sure to wash the cover if it gets dirty before the next use; otherwise, it may have the opposite effect, allowing dirt to stick to the car. How to Secure a Car Cover: Evenly spread the cover from the front to the rear of the car. First, secure the ear positions on both sides of the cover to prevent it from slipping. Then, fit the cover tightly over the front and rear of the car. After covering, pass the windproof strap under the cover from one side of the car to the other. Then, on the opposite side of the car, fasten the buckle. Finally, thread the steel cable through the metal ring and pass it to the other side, then lock the ring and cable with an anti-theft lock.

What is the size of the photo for a driver's license?

Driver's license photos must be one-inch white background photos. According to the regulations on the application and use of motor vehicle driver's licenses, the size and color of the photos have been clearly specified. The requirements include a front-facing, single-person, half-body ID photo of the applicant taken within the last six months, with a white background and clear visibility of the person. Nowadays, driver's license photos can be retouched, but the degree of retouching should not be excessive. According to the regulations, the image should be clear, with rich layers, natural facial expressions, and no obvious distortion or stretching. Photos that meet these requirements can be used. When applying for a motor vehicle driver's license, six photos need to be submitted. According to the motor vehicle driver's license file management, the resolution of the photos should be 300dpi. However, requirements may vary slightly by region. Specific requirements should be based on local policies, and photos can be taken directly at the driving school during registration. Holders of A1, A2, A3, B1, or B2 driver's licenses must report to the traffic management department of the public security authority within thirty days after the end of each scoring cycle for verification. However, if there are no demerit points recorded during a scoring cycle, the verification for that cycle is exempted.

What Causes Brake Disc Noise While Driving?

The causes of brake disc noise while driving include normal ABS activation, rust on brake pads/discs, excessive wear of brake discs and pads, and installation issues. Below are detailed explanations for each cause: The ABS operation process is actually a cycle of locking, releasing, locking, and releasing, keeping the vehicle in a state of near-lock rolling. Therefore, when ABS is activated by sudden braking, noise is normal, and pressing the brake pedal fully can resolve it. After prolonged parking, especially in humid weather or after rain, some rust or dirt may form on the brake discs or pads. Driving for a while can solve this, or applying butter or specialized lubricant at the connection between the brake pads and calipers may help. Both brake discs and pads are high-wear components. Every time you brake, these two parts experience friction, leading to wear over time. Excessive wear naturally causes noise, so regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 km, while brake discs last 100,000-120,000 km. Incorrect installation or mismatched models of brake pads can also cause noise. Reinstalling the brake pads may resolve this. Owners should have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as extra caution is needed.
